Title: Method of forming laminated single polarization fiber
Inventor: BHAGAVATULA VENKATA ADISESHAIA
IPC: G02B6/10
Filed: 1984-10-03
Granted: 1988-01-14
Abstract: A process for manufacturing a preform from which is drawn an optical fiber, the core of which comprises layers of different glass composition. Layers of glass, adjacent ones of which have different composition, are deposited on a substrate. A process is preferred whereby layers of glass soot are deposited. The soot is consolidated and the resultant laminated glass structure is severed to form an elongated azimuthally asymmetric laminated core structure. A layer of cladding glass is added to the core structure, and the resultant preform is drawn into an optical fiber.

Title: A method for recovering precious metals
Inventor: BERG HANS GUNNAR
IPC: C22B7/00
Filed: 1985-09-25
Granted: 1989-10-12
Abstract: The invention relates to a method for pyrometallurgically recovering the precious metal content, such as gold, silver and platinum metals, of halogen-bearing materials rich in silver. The material is caused to rapidly disperse in or be finely distributed throughout an at least partially molten charge containing a non-oxidic metal-containing phase having the ability to dissolve precious metals and to substantially lower their chemical activity. The halogen content of the material herewith reacts with any fluxes or metals of high chemical activity present in the furnace charge, while forming metal halogenides. The halogenides formed are separated by slagging and or volatilization, and the precious metals are recovered from the molten charge, depleted of halogens, in a conventional manner and with regard to the charge phases.

Title: Front end circuit structure for a subscriber line circuit interface
Inventor: CHEA RAMON CON WOO
IPC: H04M19/00
Filed: 1985-10-14
Granted: 1989-11-16
Abstract: A front end circuit structure for a subscriber line circuit interface employs a controllable amplifier including a switching converter. The switching converter includes a capacitor coupled across a two-wire subscriber line and supplies an auxiliary voltage to the line. The amplifier includes an input adder having an output coupled to the switching converter for controlling the magnitude of the auxiliary voltage with one input of the adder adapted to receive a feedback control signal which is developed by monitoring the voltage across the output. Another input to the adder receives line input signals for the line circuit. The amplifier is controlled in operation by an off hook detector which provides an output signal when the subscriber lines goes off hook to cause the amplifier to operate and further includes ring control logic which is also coupled to the amplifier and activates the amplifier during the presence of a ring control signal. In this manner, the amplifier is operative only during an off hook condition of the line and during ringing generation. The amplifier, based on its structure in the line circuit, provides all basic line functions such as DC current, ringing, voice and remote metering signals.

Title: Fluidized-bed exchanger for heat transfer
Inventor: LARGE JEAN-FRANCOIS
IPC: F28D13/00
Filed: 1986-04-24
Granted: 1988-12-08
Abstract: A heat exchanger comprises two fluidization chambers separately supplied with fluidization gas. A heat transfer medium in the form of particulate material is supplied to the first chamber which is in communication with the second chamber. The second chamber has an outlet for discharging the heat transfer medium and contains a plurality of heat exchange tubes immersed in the fluidized bed therein. The particles of the heat transfer medium have average dimensions between 50 and 3,000 micrometers, and the maximum speed of the fluidizing gas in the second chamber is between 1.5 times and 10 times the minimum speed of fluidization of the particles of the heat transfer medium. Adjacent heat exchange tubes are arranged to be spaced by a horizontal distance which is between 1.4 times and 2.1 times the external diameter of these tubes. Additionally, the tubes have a vertical spacing between 1.4 and 2.1 times the external diameter of these tubes. By these means efficient heat exchange between the particulate material and a fluid flowed through the tubes is achieved.

Title: Adjustable filter cigarette
Inventor: NICHOLS WALTER ALLEN
IPC: A24D3/04
Filed: 1986-11-04
Granted: 1989-10-05
Abstract: A variable dilution cigarette (40), of the type having a filter (42) with two relatively rotatable segments (44,45) having slits (62,63), (60,61) in the plug wrapping (52) and the tipping paper (43) which rotate in and out of rotational registry to vary the dilution level, is provided which is insensitive to slight longitudinal misalignment of the slits. An array of longitudinal depressions (50) is formed in one segment of the filter plug centered on the slit in the plug wrapping and ending short of both ends of the filter segment containing the slit. The depressions act as a plenum allowing the longitudinal flow of air between the slit in the tipping paper and the slit in the plug wrapping in case of longitudinal misalignment arising during use, but do not allow circumferential air flow when the slits are intentionally deregistered by relative rotation of the filter segments. Because the depressions do not reach the ends of the filter segment containing the slit, they do not allow any unwanted air into the filter.

Abstract: A digital coding process for transmitting and/or storing acoustic signals, in particular musical signals, in which N pick-up values of the acoustic signal are transformed into M spectral coefficients. The process is characterised by the fact that in a first stage the M spectral coefficients are quantified. After coding, an optimal coder checks the number of bits necessary for reproduction. If the number of bits is above a predetermined number, the quantification and coding are repeated in further stages until the number of bits necessary for reproduction no longer exceeds the predetermined number of bits. The required quantification stage is transmitted or stored in addition to the data bits. The advantage of the process is that acoustic signals in particular musical signals, can be transmitted and/or recorded without any subjective quality reduction of the musical signals with a reduction of data rate by factors of 4 to 6.

Abstract: A sampled synchronous transmission signal Vt is represented by a series of samples J at equidistant sampling instants. A computing circuit 5 computes the positions R of the sampling instants relative to the rising edges of a virtual reference clock Cref which is phase-locked to the channel clock. For each sampling instant the position R is determined on the basis of the position R of a preceding sampling instant and a measure Q of the difference in time between the sampling interval T and the period L of the virtual reference clock Cref. From the values of the successive samples J an interpolation circuit 2 derives the positions N of the detection-level crossings by the transmission signal Vt, which crosssings represent a fixed phase position of the channel clock. After each detections-level crossing the measure Q of the time difference is corrected by means of circuit 3 and 4 depending on the difference between the positions N and R. A data recovery arrangement recovers the data depending on the values determined for the positions R.
